That's really odd! It's quiet until the program starts? What happens if you run 10 and X concurrently? Start up 10 first, it's quiet, then start X?
Audio config on X is identical to 10? HA!! Try turning off CAT control in WSJT-X. I bet the program is changing something on the rig to make the noise come up. 73, Josh W6XU Sent from my mobile device > On Jan 6, 2018, at 11:35 AM, Dave S via Elecraft <[email protected]> > wrote: > > After I installed the KIO3B board in my K3, I found that running WSJT-X > creates 2 or 3 S-units of noise in the rig but WSJT 10 runs quietly.Tried > different computers, different cables, different jacks, and scads of ferrites > on the USB cable.
